VISE.

Specification of Letters- Patent.

Patented May 21, 1907.

Application filed December 11,1905. Serial No 291,202.

To all whom it may concern:

Be it known that I, MiroHELL J. HILBERG, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Vises, of which the following is a specification.

The object of my invention is to produce a vise, which will be simple in construction, cheap of manufacture and eflicient in use. It

. belongs to that class of vises in which the ordinary screw and turning handle used to move the movable jaw to or from the stationary jaw are dispensed with; this operation being very slow.

My invention consists in providing the movable jaw with a rack a pinion lover or notched lever or handle engaging said rack to move said movable jaw to and from the stationary jaw; and providing means for holding the movable jaw in a fixed position when the work has been bound or tightened in place.

My vise is operated more quickly, its operation is more positive and effective, can be handled more readily, is more compact, the article to be placed between the jaws will be held more tightly and rigidly and can be more quickly removed from the jaws.

In the accompanying drawing forming part of this specification. Figure 1 is a top or plan view of the vise, the top piece being removed to illustrate the interior construction. Fig. 2 is a side view of the vise. Fig. 3 is a rear end view of the vise.

The body of the vise is composed of a stationary jaw piece A, a movable jaw piece B, and a top piece O. The jaw piece A is a casting, having a bottom A and side parts A A thus forming a channel or passage way, in which movable jaw piece B may move for- The movable jaw piece B is a casting composed of along flat bar O having rigidly attached to its upper side a steel rack D. This rack bar is riveted to the bar O of the jaw piece B and at its for ward end the rack bar D passes through the jaw B a nut D being screwed onto it, to rigidly hold the rack D in place and keep it from buckling. The stationary jaw piece carries at its forward end jaw B and the movable jaw piece B carries at its forward. end the jaw B Of course the stationary piece A is hollow or slotted at its forward end to allow the movable jaw piece B to move in and out. This can be seen in Fig. 2, where the slot is marked E. The bottom or stationary jaw piece A is screwed to the bench or table by screws passing through small eyes or wings F. The top piece O is screwed onto the side pieces A A of stationary piece A by screws passing through the eyes or wings G. The stationary piece A carries at its rear, on one side a pin H. The movable piece B is slotted on one side for a certain part of its length (at its rear end) this slot being designated by the letter K. This slot is shown in dotted lines in Fig. 2. The purposes of this pin H is to keep the movable piece B from sliding out too far, as when the end of the slot is reached, it strikes pin H and the forward movement of movable piece B is stopped.

At L one of the sides A of the stationary part A is broken away (see particularly Fig. 1.) To one of the side pieces A of the stationary piece A, I attach at each end thereofby screws M a segmental or semicircular ratchet N, having teeth N In the broken away portion L of side A is formed an elongated eye P, an eye P also being present in the top piece O directly in line with eye P, (see Fig, 2). A pin R passes into these eyes P & P.

S represents a hand lever or pinion lever formed like a handle and at its forward end carrying a toothed head similar to a pinion, designated by letter S. The teeth on this head S are marked T. The pinion lever S is pivoted or fulcrumed in slots or eyes P, P, by pin R.

The teeth on the rack or bar D are designated by the letter V. The teeth T on the head S of the lever S mesh with the teeth I on the rack D, and move said rack D in and out in the stationary piece A, consequently the jaw B is moved from or toward the jaw B A pawl II pivoted at IV to the handle or lever S and. governed by a grip or movable handle Y, works in the teeth N in the ratchet N. This handle Y is connected to pawl II by a spring connection and pin Y (see Fig. 3) so that when the handle is in normal position the pawl II will always lie in the teeth N of the ratchet N. By pressing on the handle Y and forcing it toward the lever S the pawl IV through agency of the connection I is raised out of the teeth N of the ratchet N, and while this position is assumed, the lever S can be freely moved forward or backward uninterrupted by the ratchet teeth I. By moving the handle or lever S backward, the teeth T on head S will mesh with the teeth V on rack D and the movable jaw piece B carrying the jaw B will move forward, and by working handle or lever S forward the jaw piece B will be moved backward. By working the lever S backward until the blank part Z on the head S of the lever S is reached, the jaw piece B can be moved forward. or backward without interruption or interference. The pieces Z Z are placed in jaws B B, so as to be removed or replaced by similarly shaped parts or pieces, the pieces 71 Z being of various degrees of hardness, according to the work required to be done on the vise, as for instance if brass is to be worked in the vise the pieces Z r will be of soft material, if steel is to be worked, they will be of hard material. A lug X is present at forward end of the lower part of the stationary jaw piece A, so that the vise cannot move backward in use, as the lug X impinges against the side or edge of the bench and prevents backward movement.

It will be readily seen how the vise operates. The lever S is so turned that blank part Z of its head will be opposite the teeth V of the rack D, the movable jaw piece B, carrying jaw B will now freely move in and out or to or from the jaw piece A carrying the jaw B; when the work is placed between the jaws B & B the operator grasps the handle or lever S, and forces the grip handle Y to be pressed inward, thus disengaging the pawl from the teeth V of the ratchet N, the lever S is then pressed or pulled forward, thus the teeth T of the head S on lever S will mesh with the teeth V on rack D of movable jaw piece B carrying jaw B and force it back ward, consequently the jaw B will impinge against the work and force it tightly up against jaw B and firmly hold it in place, the handle Y is relaxed and the hold on the lever S released, thus the pawl W will fall into the teeth N bf ratchet N and prevent any further movement of the movable jaw piece B carrying jaw B The vise can be of any style, shape, size or contour and made out of any material. Any form of mechanism may be employed to hold or release the pawl from, the ratchet, in fact, any mechanism may be used to regulate the operation of the movable jaw piece C. The parts of the vise may be held in place and together in any desired manner. The head on lever S may be of any shape desired.

What I claim as new and of my invention and desire to secure by Letters Patent is:

1. In a vise, a stationary jaw, a movable jaw, said movable jaw sliding in said stationary jaw, a toothed rack, said toothed rack connected to the movable jaw, a lever, said lever pivoted on the stationary jaw, said lever carrying-teeth at its forward end, the teeth of the lever meshing with the teeth on the rack, a semi-circular ratchet immovably connected to the stationary aw, said ratchet, lever and rack lying in practically the same plane, a pawl, said pawl connected to the said toothed lever, said pawl engaging or disengaging the ratchet through mechanism attached to said lever, the mechanism for oper ating the lever an d the pawl capable of simul taneous operation in hands of operator, as set forth.
